12 moles are needed because stoichiometry is 1:2
D
Mass of N₂ will be formed : 50.12 g
<h3>Further explanation</h3>
Reaction
2 NH₃(g) + 3 CuO(s) → N₂(g) + 3 Cu(s) + 3 H₂O(g)
moles NH₃ = 3.58
ratio mol NH₃ : mol N₂ = 2 : 1
so mol N₂ :

mass N₂ (MW=28 g/mol) :

Answer:
sodium pentanoate and ethylmethylamine
Explanation:
The reaction of N,N-ethylmethylpentanamide with sodium hydroxide involves an amide and an inorganic hydroxide.
The CO-N bond is highly polar hence the -N(C2H5) (CH3) moiety is easily lost and replaced by the -ONa leading to the formation of sodium pentanoate.
The H^+ combines with -N(C2H5) (CH3) to yield ethylmethylamine
It doesn’t let me see the picture it’s blurry.

What is pH and its importance?
- pH is an important quantity that reflects the chemical conditions of a solution.
- The pH can control the availability of nutrients, biological functions, microbial activity, and the behavior of chemicals.
- The pH is then calculated using the expression: pH = - log [H3O+].
- The solubility of an ionic compound is affected by the hydronium ion concentration.
- Addition of H₃O⁺ to the anion of a weak acid, increases the solubility of the ionic compound.
Therefore, the pH of the solution is also increased.
